What is it about the Eldar that motivates you? Models? Fluff? Extremely powerful codexes/codecies in nearly every edition?

I have about 2k worth of Eldar that have been sitting in a box since 2009 or so because I cannot find motivation for them. I bought them from a friend who was leaving the hobby...thinking that I would get them restored and painted up. I really want to do something with them just to give myself an excuse to buy Eldar titans...which was my major motivation for buying them in the first place...I want to own/build/paint a Phantom...an armorcast phantom would have been my first 40k model if I had had another $100 on me when I found them (opted for a warhound)

In any case, please tell me what it is that you love about them.
